That would enormously helpful to me in narrowing down the reasons for this odd behavior. As more students update to Sierra I expect to get more of these reports.

After using iGlasses, I was able to see the C615 camera preview perfectly, and I confirm that it works with TVPaint Animation Standard Edition.

Ok, I've found something. If I'm drawing and I get a notifications from another app, my crosshair turns into a cursor. V.annoying if I'm doing something delicate...

I'm having this also on 11.0.6 standard edition Mac OS 10.12.5 .. Actually not sure about notifications, but If I switch to any other application, when coming back to TVP I get the cursor. I found I can get back the crosshair by pressing CMD + O (open dialog) and closing it.
